Multiproperty Atomistic Characterization of a Synthesized Pyrazinic Nitrogen-Doped Porous Armchair Graphene Nanoribbon
Cicera M. V. de Araújo, Isaac de M. Félix, Willian F. Radel +4
Graphene nanoribbons (GNRs) obtained by on-surface synthesis combine a width-controlled band gap with atomic precision, making chemical decoration of their edges and interiors a pr…

Ion-Engineered Insulator-to-Semiconductor Transition in Natural 2D Biotite
Dipanwita Mitra, Raphael B. de Oliveira, Guilherme S. L. Fabris +7
Naturally occurring layered silicates offer an abundant yet unexplored class of 2D materials, but their insulating nature limits their functional utility. Here, we demonstrate a ch…

Ambient-Induced Selenium Segregation and Nanoparticle Formation in 2H-HfSe2: An Experimental and Theoretical Study
Stefany P. Carvalho, Guilherme S. L. Fabris, Ana Carolina F. de Brito +7
We investigate the air-induced degradation of few-layer hafnium diselenide (HfSe) through combined experimental and theoretical approaches. AFM and SEM reveal the formation of…
